Abstract:
Objective To explore the prognostic value of hyperdense artery sign(HAS)in elderly patients with acute anterior LVO in anterior circulation undergoing mechanical thrombectomy.Methods A single-center retrospective analysis was conducted on 109 patients with acute LVO of anterior circulation admitted in our department from January 2019 to December 2022.According to their preoperative plain CT scans,they were divided into HAS positive(39 patients)and HAS negative(70 patients)groups.Baseline features,surgical indicators,complications and outcomes were compared between the two groups.Results The patients with HAS had significantly larger proportions of atrial fibrillation and symptomatic intracranial hemorrhage than those without the sign(53.8％vs 31.4％,20.5％vs 5.7％,P＜0.05).The rate of 90-day good prognosis was a little higher in the HAS positive group than the negative group,though no statistical difference(48.7％vs 38.6％,P＞0.05).Male,stroke history,SBP,NIHSS at admission,HAS positivity,revasculiza-tion,and symptomatic intracranial hemorrhage were independent influencing factors for favorable prognosis in the patients(P＜0.05,P＜0.01).Conclusion The presence of HAS is a prognostic marker for patients with acute LVO in anterior circulation undergoing mechanical thrombectomy,and it is associated with a higher risk of symptomatic intracranial hemorrhage.
